`COLOR-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 723,736, dated March 24, 1903.

Application tiled August 22,1902. Serial No. 120,717. (No model.)

To all whomV it may concern.'

Be it known that I, GEORGE SCHNEIDER, a subject of the Emperor of- Germany, and a resident of Berlin, Germany, have invented a new and Improved Color-Printing Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved color-printing machine for printing oil-cloth, wall-paper, and like fabrics, arranged to permit convenient and quick insertion or removal of the printing or pattern rollers, minute adjustment of the printing-rollers and the color-supplies, and to give access to the color-supplies for cleaning, repairing, or other purposes, thus facilitating all work necessary before, during, and after the printing operation.

The invention consists of novelfeatures and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

roller. Fig. 3 is an end view of the same. Fig. 4. is a side elevation of the means for imparting rotary motion to the color-distributing roller. Fig. 5 is an end View of part of the same. Fig. 6 is an end view of the means for adjusting the scraper for removing the surplus ink from the ink-supply roller, and Fig. 7 is'a side elevation of the same. is a fragmentary plan view showing certain details in section and illustrating the gearing of the rollers K. Fig. 9 is a view somewhat similarlto Fig. 2 and shows the mech-y anism for imparting axial motion to the colordistributing rollers. Fig. l0 is a rear elevation of a portionof the bed 8 and the gearing mounted thereon, and Fig. 11 is an elevation viewed from ythe opposite direction and showing a mechanism for actuating the several links L3. Y

The bed A of the color-printing machine is provided with longitudinally extending guideways A', on which is mounted to slide a frame B, carrying in its side arms bearings C for an i'mpressioncylinder D, the said frame B also carrying bearings E, in which are jonrnaled 4printing or pattern rollers F for printing the desired design on the fabric passed between the impression-cylinder and thes'aid printing-rollers. Theprintingorpattern rollers F are in engagement with colordelivering rollers G, preferably arranged in pairs and forming parts of color-supplies H, of which there is one for each printing-roller F, each color-supply being held on a slide I, mounted to slide on a frame J, iixed to the bed A, each slide being adjustable by a screwrod I', as plainly indicated in Fig. 1..

The frame B, carrying the impression-cylinder D and the printing-rollers F,is movable on the guideways A', and for this purpose the frame B is provided With a rack B', in mesh with gear-wheels B2, secured on a shaft B5,

extending transversely and journaled in suitable bearings carried by the bed A. A crankarm B4 on the shaft B3 enables the`operator to conveniently turn the shaft BSto cause the gear-WheelsB2 to shift the rack B', and with it the frame B, tothe left or to the right, so as to move the impression-cylinder D and the printing-rollers F bodily toward and from the color-supplies-that is,their delivery-rollers G-to give convenient access to the printing-rollers whenever it is desired to remove and replace the same by others or Whenever it, is desired to change from one piece of Work to another. Fig. 8 j

The impression-cylinder D has a minute adjustment relative to the printing-rollers F, and for this purpose the usual eccentric adjustment Cis provided, connected with the bearings C, as plainly indicated in' Fig. 1, to shift the bearings C on the frame B. Each of the color-supplies H is provided with an ink-distributing roller K, mounted to turn and to slide transversely in bearings on the slide I, the said distributing-roller beingin contact with the delivery-rollers G, which supply the color to the printing-rollers F.

By having the ink-distributing rollers and the impression-cylinder adjustable toward and from the prin ting-rollers provisionis made for employing dierent-sized printing-rollers and the interchanging of the said rollers permitted at any time and Without in any wa)v interfering with the other parts of the machine.

Now in order to impart an axial movement tothedistributing-roller K the shaftK thereof is engaged at one end by a fork L, mounted to swing with and to slide longitudinally on a rock-shaft L, journaled in suitable bearings on the frame J, the shaft extendinglongitudinally in the direction of the movement of the corresponding slideI. On oneend of the shaft L is secured an arm L2, connected by a link L2 with the arm L2 of the next adjacent rock-shaft L' of the adjacent color-supply H, and one of the said rock-shafts L' receives a rocking motion from the main shaft of the machine, so that all the rock-shafts L' of the several color-supplies H are rocked in unison to impart a transverse rocking movement by the forks L to the several distributing-rollers K.

By inspecting Fig. 8 it may be seen how the links L3 are moved in unison. The shaft K (shown perhaps to better advantage in Fig. 8) carries a key K2, movable with the shaft through the hub K3 of the bevel-Wheel N, the shaft K' being prevented from axial Inoveinents by the rear frame of the slide I. A pinion on said hub arranged on the inner side of the frame serves to rotate the auxiliary rollersarranged around.the roller K. (See Fig. The fork L, therefore, produces the axial movements of the roller K.

For preventing the gear N from unmeshing from the gear N' the hub N2is provided With an annular groove engaged by a bracket n, secured to the rear end of the slide I.

The gear N is free to move relatively to a key o upon the shaft O when the wheel N is moved radially. From Figs. 8 and 9 it may be seen that by means of the screws K Ks the cheek-pieces K are loosely held in the annular groove K7 of the shaft K', so that the motion of the fork can be transmitted.

Referring to Fig. 10, it may be seen that by means of the driving-shaft a and bevel-Wheels shown a shaft b is rotated. The rotation of the shaft b drives the shaft c. The bevelwheel CZ of the shaft c meshes With the bevelwheel P of the shaft O.

Referring to Fig. ll, it may be observed that the shaft a rotates a shaft e, having a crank on its lower end connected with a pitmanf, this pitman being connected with a part g, pivoted to the arm L2 of one of the shafts L. The several links L2 for moving the other shafts L are also connected with the pivoted parts g".

In order to impart rotary motion to the several distributingnollers K of the colorsupplies H from the main driving-shaft of the machine, I provide the following device, special reference being had to Figs. l, 4, and 5: On each shaft K is secured abevel gear-Wheel N, in mesh with a similar bevel gear-wheel N', mounted on a shaft O, journaled in suitable bearings, of'which one is secured on the slide I and the other on the frame J, and on each shaft O is secured a bevel gear-Wheel P, in mesh with a bevel gear-wheel P', secured on a shaft P2, journaled in suitable bearings on the frame J and carrying a second bevel gear- Wheel P2, in mesh with the bevel gear-Wheel P, secured on the shaft O of the next adjacent color-supply H, so that when one of the shafts O or P2 is rotated from the main driving-shaft of the machine it is evident that all the shafts O of the several color-supplies are rotated in unison to rotate the distributing-roller K.

By operating the several sets or groups of ink-distributing rollers one from the other and the first set or group from an independent drive-shaft the sets or groups can be readily connected or disconnected to permit of using a greater or less number, as desired, and the rollers of the several sets or groups kept re volving when the impression-cylinder alone or with the printing-rollers has been moved outward away from the ink-distributing rollers for repairs or otherwise, thereby permitting the ink to be kept at the proper consistency and to be evenly applied to the printing-rollers before the paper is brought into contact with the same.

ISO

By withdrawing the impression-cylinder from the print-ing rollers and leaving the printing-rollers still in contact with the inking-rollers and keeping all in motion except the impression-cylinder the operator can see not only how the inking-rollers grind and distribute the ink, but also With what consistency the ink is delivering to the whole surfaces of the printing-rollers and can regulate this to the exact requirement before bringing the impression-roller and paper in Contact with the printing-rollers.

The color-supply roller Q of each color-supply I-I is engaged on its peripheral face by a scraper or knife R for removing the surplus color, and this scraper R is mounted to slide longitudinally on the slide I and is provided with screw-rods S, on which screw Wormwheels T, in mesh with Worms T', secured on the sections U and U2 of a shaft U, having the sections Ul and U2, supported by a bearing U3, which permits of turning the sections Ul and U2 either in unison or one independent of the other, so as to adjust the scraper or knife R relative to the color-supply roller Q to insure a proper scraping of the said roller. Each section U U2 carries a small hand- Wheel U4 U5 for adjusting its scraper independently of the other.

By the arrangement described the operator on turning the shaft U or U2 causes a parallel movement of the scraper or knife R IIO IZO

vamer/:ae

toward or from the color-supply roller Q to insure a minute adjustment of' the scraper R relative to the peripheral :face of'the colorsupply roller Q( By turning the shaft-sections U U2 independently either end of the scraper may be moved toward or from the roller Q to insure' a proper initial setting of the scraper relative to the roller.

It is understood that the color-supplies H are arranged on one side of the impressioncylinder only to allow bodily movement of the impression-cylin der and the printing-rollers toward or from the said color-supplies H on moving the frame B inward or outward by the operator actuating the rack-and-pinion movement. Thus when the frame Bis moved outward sufficient space is left between the color-supplies H and the printing-rollers to allow convenient exchange of printing-rollers and to permit making repairs, &c. When the frame is moved inward, the printing-rollers are brought in proper 'contact with the color-deliveryrollersG. Byhavingthecolorsupply slides or frames I adjustable on the frame J a final minute adjustment also can be had between the color-delivery rollers G and the printing-rollers.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl.
